Travis Nielsen 72a4245fbf mon: improve mon failover reliability ...

Mon failover reliability is improved in two scenarios with these changes.
First, if the failover is aborted because of failing to start the new mon
and wait for it to join quorum, the new mon will be fully removed and
the failover rolled back. Previously, the operator would leave the new
mon pod running even if it never joined quorum. Now the timeout for the failover
is increased to wait longer for the new mon, but if it times out, there
are no leftovers from the cancelled failover.

Second, if the operator is failed in the middle of a failover
before the old mon is removed, the operator needs to remove an extra
mon. The operator was only selecting a random mon for removal instead
of honoring the stretch cluster topology or looking for mons
on the same node that could be removed to restore the correct
desired number of mons.
